Laminate to use throughout the year. This is a great file folder activity. Students determine how many circles to add to get to the total of 10. The first page has rows of 10 spaces with some filled with circles. Students choose the correct circle to match the row and count how many they need to get to a total of 10. The second page gives sets of 10 of each circle pattern. These can be cut to complete the chart. The last page is filled with blank rows with 10 boxes. You can place a given number of circles in the box and ask the student to find the number needed to total 10.
